A modern foot soldier marches with 90-120 lbs (40-55kg) of body armor, weapon, ammo, radio, rations and other items. That's a lot more than a fully armored high middle ages knight or sergeant at arms would carry.

All those who are merciful with the cruel will come to be cruel to the merciful.

Definitely tougher for the modern soldier considering the knight got around on a horse and his squire to carried everything else!

It seems like a simple concept that would be lightweight, small, warm, and quick to setup. With a suitably tough exterior material it should be relatively durable. Until someone drops a knife on it anyway, but a tire repair kit or similar would seem to remedy that easily enough.

It seems like it would be warmer than a cot. Air is a pretty good insulator when it isn't blowing around. It would be a captive pocket of air in this thing as opposed to free flowing air that never warms up on a cot.

I've found air filled mats and pads to be cold in cold weather when on the ground. Any heat that might be absorbed by the air from your body just gets sucked out by the ground and the air is cold all over again. Until you bleed more of your warmth into it, then the cycle continues.

Kind of the same idea as a wetsuit; I always thought a wetsuit would be cold since you're allowing cold water to get into the suit and next to your skin, but once the water gets into the suit and warms up, it acts like a layer of insulation.
